The Urban legend might not be true but many moons ago i had a fisher Tri space pen black,red and pencil unfortunately lost now but it gave me hours of fun watching people who had "borrowed" it try to figure out how to switch between the colours at the University i was working at at the time as it had only one button that pushed selected option in and out..... ..

The mechanism to select the colour on my fancy space pen was a simple gravity feed.

Well, when I say invented, more of a collation from a number of other languages really, but I guess it's called English for a reason.

Also rather rash to paint the whole population with the same brush. I can, for example, spell in both the UK and US variants of English (Although I choose not to use the second even though I work for an American company). I am British by the way.
